`This invention pertains to baby carriages and more particularly tomeans for adjusting the position of the handle bar to differentelevations.

In accordance with this invention, generally stated, the handle-bar ispivotally 'supported on the frame of the baby carriage so that it may bemoved on its pivot to diierent positions. An alignment plate is looselysupported on the frame on the same pivot as the handle-bar and ismaintained in alignment with respect to the frame by engagement with afixed supporting member on theframe. Said plate is yieldingly retainedin position by .a spring on the handlebar pivot but may be movedlaterally of the frame without losing engagement with said supportingmember. This alignment plate is provided with a plurality of sockets andthe handlebar has xed thereon a complementary keeper or detentengageable in one of said sockets. When the alignment plate is sprungoutward from the frame, it can be moved clear of said keeper so that thehandle-bar may be shifted on its pivot and the keeper engaged in any ofsaid sockets, thereby changing the elevation of the handle.

A preferred embodiment of this invention is illustrated in theaccompanying drawing, in which Fig. 1 is a side view of a baby carriagehaving an adjustable handle-bar embodying this invention;

Fig. 2 is an enlarged view of a portion of the frame and the handle-barat the junction betweenthe two; and

Fig. 3 is a section on line 3-3 of Fig. 2.

Referring to the drawing, the baby carriage illustrated comprises aframe I which may be of the folding type mounted on wheels 2 and havinga body 3 of any suitable type, in which the child may ybe c-arried. Apair of handlebars 4. only one of which appears in the drawing, carriesbetween them a handle 5 in the usual manner.

The handle-bar 4 -is mounted on the frame I by a pivot pin 6. Alsoloosely mounted on the pin 6 is an alignment plate 1. A secondsupporting pin 8 is fixed on the frame I and is movably engaged in Iaperforation 9 in the plate 1. The pins 6 and 8 support the plate 'I andmaintain the same in alignment with respect to the fr-ame I.

Between the head of the pvot pin 6 and the plate 'I a spring washer I0is mounted on the pin so as to bear upon the plate 1 to keep it pressedaga-inst the frame I. The plate may,

however, be moved outward against the tension of the spring I0 asindicated in dotted lines in Fig. 3. When moving to this position, theplate moves with respect to the pin 8 but does not lose its engagementtherewith so that its alignment is maintained. The plate 'I is formedwith a plurality of slots II forming sockets for engagement by a detentor keeper I2 xed to the handle-bar 4. As will be clear from Fig. 3, thekeeper I2 is clear of the sockets Il when the plate is moved to itsdotted line position. Accordingly, the handle-bar 4 may then be moved upor down so as to locate the keeper I2 for engagement with any of thesockets II. When the plate is released and returns to its full lineposition, Fig. 3, the engagementV of the keeper I2 with its socket xesthe position of the handle-bar 4.

It will be seen that this invention provides a simple .and rugged-construction for providing kadjustment for a handle-bar of this type.The -pl-ate 1 is maintained in alignment by the pin 8 which provides afixed lalignment member which is movably engaged by said plate so as tomaintain the alignment thereof while the plate I is moved for permittingadjustment of the handle-bar. The plate `'l thus fixed in alignmentprovides a cantilever by which the handlebar 4 is supported through theengagement of the keeper I2 with one or the other of the sockets II. Itwill be noted that the head portion I3 of the plate I is enlarged so asto project laterally beyond the sides of the handle-bar 4 to provide athumb-piece against which the operator may press to move the plateoutward for adjustment of the keeper I2 from one socket to another. Oncethe keeper has been engaged in a socket land the plate 1 released, thehandlebar is rigidly held in its adjusted position.

Various changes may be made in the details of construction, within thescope of the appendded claims, without departing from the spirit of thisinvention. Parts of the invention may be used without the whole andimprovements may be added while retaining some or all of the advantagesof the invention.

I-claim:

1. An adjustable handle-bar for a baby carriage having a frame,comprising, a handle-bar pivoted to said frame, a plate loosely mountedon the lpivot of said handle-bar, an alignment pin xed on said frame andloosely engaged in a perforation in said plate to x the alignment of thelatter while permitting movement thereof transverse to the plane of saidframe, a spring on said pivot adapted to restrain such transversemovement, said plate having a plurality of sockets in diierentalignments, and a keeper on said handle-bar engageable with any of saidsockets.

2. An adjustable handle-bar for a baby carriage having a frame,comprising, la. handle-bar pivoted to said frame, a cantilever movablysupported on the pivot of said handle-bar and movably engaging a `secondsupport on said frame adapted to maintain said lcantilever in fixed.alignment with respect to said frame While permitting movement thereoftransverse to the plane of said frame, a spring on said frame adapted torestrain such transverse movement, and a supporting connection betweensaid handle-bar and said cantilever, said connection being shiftableupon such transverse movement of said `cantilever '4,4 to vary thealignment of said handle-bar with respect to said frame.
